TEXT: I am currently directing a research project pertaining to motorcycle conspicuity. We have developed, and are testing a Motorcycle Conspicuity Enhancement System (MCES). A copy of the paper, which I will present at the Annual Human Factors and Ergonomic s Society (HFES) meeting next month, is enclosed.

As a human factors and safety consultants we have been asked to investigate several cases where a lack of motorcycle conspicuity has been a factor in accident causation. The development of the MCES was inspired by these cases. It is designed to attach t o the front of motorcycles to enhance visibility using a series of small lights (xenon strobes) that are supplemental to the headlight.

The MCES was built by Dr. Brian Andresen, Director of the Forensic Science Center of Lawrence Livermore National Laboratory. We are are in the early stages of considering patenting the MCES and hope to make it available to motorcycle riders.

In reviewing the laws pertaining to motorcycle lighting, we understand that this system may only be used during daylight hours and may not affect the headlight. If there are any additional regulations pertaining to this system of which we should be aware , please contact me directly at (619) 434-4741.
